To find out some more about how the forum works… there should be a message from the discobot 
in the personal/private message area… just read it…
If not… then just write it a message ( Profile → Summary → Messages → New Message) and write to @ followed by discobot… actually there is a completion funcion…
You might be noticed that this “member” wasn’t saying much for a couple of month and you might want to use another contact method… but don’t bother… discobot doesn’t even have to sleep… 
Don’t forget a topic and you also will learn that the message has to be more then 10 character…
You proberly get an anser like:
…say
@discobot display help
or you also even to so in the first place…
