if you post right into the thread - and just say 'hi' or something, it should work.... are you using the BB app or tapatalk??

(I found it easier just to use safari on my phone (a bit more awkward, but without the quirks of the apps.... a few things need fixing in them still!)
after you have posted more than 50 times and been a member for more than a month, more things open up and it's easier to post... so just keep saying Hi and commenting with others and it will get there
