Just making sure now for any possibilities:
Did you literally place this text in your regs.ini?
[Messages]
User1=..
User2=..
Does your event have a # labeled?
on *:join:mychannel: {
try typing this into your chat:
/writeini regs.ini test testing message thingy now
And see if something looks odd in the file.
I'm so sorry to take ur time, i just realized my own misstake..
I had not put a # inforont of my channel.. Thanks for ur help and patience! (Beginners misstake? >.<)
