Excellent Experience! Only suggestion is that PDFiller should offer free services to individuals and that will prompt businesses to buy your subscription just like many other online tools are offering, for example, FreeConference, GoToMeeting etc.

Good so far; expensive, however, AND when I agreed to your discounted one year offer when I intended to cancel after one month, I didn't realize the sum offered was in addition to the $20 one month fee, so it didn't turn out to be such a great deal after all. I was canceling, because I honestly don't see myself using this much more if even ever again. However, for the discounted rate (WITHOUT the $20 added in), I thought 'why not?' I am going to evaluate over the next couple weeks to see if I really DO want to continue a subscription, discount or otherwise.

I made a mistake and accidentally signed up for this service. When I got the **** for $96, I was shocked. I thought it was going to be such a hassle and was so pleasantly surprised. I got a full refund within an hour of writing to them with a very nice note.

What is upgradable proxy?
As described in the previous sections, upgradeable contract instances (or proxies) work by delegating all calls to a logic contract. However, the proxies need some functions of their own, such as upgradeTo(address) to upgrade to a new implementation.
Can you modify a smart contract?
Ethereum smart contracts are deployed in the Ethereum Virtual Machine (EVM), a Turing-complete virtual machine that enables the execution of code on the blockchain. A basic rule of the EVM environment is that contract code cannot be altered after deployment, which explains why smart contracts are labeled "immutable."
How do you deploy an upgradable contract?
We pass a couple of parameters to the deployProxy. First the variable that holds the contract we want to deploy then the value we want to set. The initializer function is provided to us by upgrades, and whatever function we pass to it will be executed only once at the time of the contract deployment.
What is upgradable contract?
Upgrading a smart contract does not mean we modify the code of a smart contract that is deployed—it means we swap one smart contract out for another. We do so in a way that (in most cases) means the end user does not have to change how they interact with the dApp.

Can smart contracts be modified?
Smart contracts in Ethereum are immutable by default. Once you create them there is no way to alter them, effectively acting as an unbreakable contract among participants.
