hey t-b!
thanks for the Telegram-link you provided .. this works just excellent! (I probably should've 'conducted' a research on my own :$ ).
however, thank you again for this useful hint

about Telegram vs. Whatsapp: thanks for pointing out that having both installed is possible, so no need to actually make a 'decision'. the most important thing is that this thread is for sure not the right place to start a 'flame-war'. at first, I thought switching to a Telegram-version would be a good idea even if it only makes 5% of the current yappari-user (I'm aware this aren't the same which would roughly translate to 5 people, I suppose.. ) happy when (and this condition is important) the only other option would be having no yappari at all. but as there now exists a working Telegram-plugin for 'our' pidgin, I'd also say, a Whatsapp-implementation would be the only goal of real help/use/merit.

cheers @all
