OK, sorry for being silence for long. I become involved in two projects which took lot of my time. I was hoping to reach a better state before sharing source code, but as it took much longer than I anticipated, I'm sharing it right now. The code is accessible here: https://gitlab.com/hedayat/MeeTeleGram Contributions are welcome. Hopefully, I'll start continuing it again very soon. Currently, it can connect and show your contact list, but nothing more. Edit: I just found that I've not added tgl as a git submodule to the repo. Currently, you should clone my own tgl repo (https://github.com/hedayat/tgl) inside tgl/ directory, and switch to devel branch. Regards, Hedayat
