There is no way that I know of to leave public groups. When you post in one of these you automatically become a member and I've never seen an option to quit such a group.
go to elten api programs and rewrite the forum class and reinitialize it. You can do it but you need to know ruby, and you really neadn't to recompile elten.
Remember how I managed to record long audio posts to the limited chat? Its because I wrote an elten program that reinitializes the class with the opus recording thing and just removed the time limit there. made it dummy.
I don't encurage to do that guys, I just give an example how we can reinitialize and rewrite some elten parts without recompiling. 1. create a folder in your elten programs directory, usually appdata\roaming\elten\apps. name it like you want. then create the __app.rb, but I actually forgot what config do we need to write there. in the latest elten source code, you find the whole class with what you want, copy it and paste in the rb file. Than you need to edit things there. Great, we just changed something in the elten code by tricking the ruby.
@marc, first, at least he send helpful stuff and not only stupid comments wich are not helpful, and also, he spams not, so I don't have a problem with it.
