Directions to find the form to be edited could be more simple and spelled out. Through trial and error, I was able to edit the form to my satisfaction. Thanks.

Great tool in a pinch! The google chrome extension worked really well since you can't just click on something in drive and easily open it - and I've had issues with Adobe for some time. This software did what I needed it to do multiple times. This is typically slow to open, and saving & retrieving files is a bit clunky.

PDFfiller is the best program to view and edit PDF documents. It is a tool for professionals. This program provides efficiency and quality at a very affordable price. Is it worth the investment. The one year package is very good. I recommend it. PDFfiller is a very useful application to send and receive files in PDF format, create refillable forms and sign documents in a very simple way. Its "autocomplete" function makes the job easier. It is a very light software that does not occupy a large space in our team. Sometimes pop-ups become a headache. They are somewhat uncomfortable. I think it's an aspect to improve

Great online chat support! Support when I've needed it has been great which I can rarely say about most companies these days. While the program tends to be a little cumbersome it works for what I need it to. When I have issues the online chat support has been great an very little wait to get to someone. John resolved my issue over the weekend and Kara fixed the one I had this morning - I really appreciate both their help!

Simple tool that increases productivity in office I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office. My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed. I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.

Wax seals made from modern sealing wax will not break in the mail. The key is to make sure your sealing wax is flexible, as this will add the durability required to survive being mailed. In days of old letters were hand carried and a wax seal was meant to keep the content confidential.
Please remember that adding the weight of a wax seal to your mailed item may increase the postage required for mailing. Please consider using your seal on the inside of your mailing to avoid seal damage, as well as extra handling costs from your postal office.
It may be possible to use regular candle wax, by the way, but because it lacks resin, candle wax will not stick as well on the paper, nor hold up too much handling. It's not recommended. You don't have to go either or on sealing waxes.
1: Using a butane torch, heat up the end of the wax stick until it melts. Drip the blob of melted wax onto the object you are sealing and stamp it with you seal. 2: Cut the amount of wax you want to make a seal with and place it in a spoon.
There can be 2 reasons why the sealing wax is jammed in the engraved lines of your stamp and makes it sticky: 1) your stamp is too hot, 2) you lift the stamp too soon that the sealing wax has not been properly hardened. Either of the issues you are having, the solution is the same — cool the stamp off.

Eh, yes and no. Technically, candle wax can be used to seal an envelope shut. But it's a big, but it might not withstand the mailing process. It could break, melt or leave oil stains on your invitations before it ends up in your guests' hot little hands.
