This is my first time logging into this forum and I only write in this topic the first generic things I want to say, no need to answer me, it is just as an introduction.
I have been using Deltachat for a while, I tried it after reading about how it works and I must say it is brilliant.
Some of the features I think are nice:
- development is transparent and the people behind it look like people and not robots. This means that it is very easy to share decisions made by the development team.
- decentralized and federated by default, you can choose who you entrust your data to or even open your own server with already standard procedures
- your messages are encrypted and you can control it since you have access to your databases (webmail) unlike other chats
- I also use it to check my emails and sometimes to send them (although the support is not 100% complete, to send a simple email is more than enough)
- I see very interesting new features developing even though at the same time everithings remains very simple and rational, kudos!
I also tested with a simple firewall the client communications and I must say that there is a great peace and tranquility in deltachat 
I joined because I wanted to ask some questions and another surprise, you can use the forum by logging in with your deltachat account! great!
Only thing I want to add here is that I only succeeded with a “nine.testrun” account while I had not succeeded with a “bcc.chat” account, However, I don’t know if it was simply because I didn’t have enough patience to wait for a response from the data-identity bot, so don’t take me seriously if this is something that seems incorrect to you!
That is all, W deltachat!
