Just playing around, testing discourse. So far so good.
Not sure about having a title that must be atleast 15 characters long…?
regards,
Nick.
I guess the developers of discourse figured if you couldn’t come up with 15 characters for the subject line, you must not have enough content to warrant posting something 
(Yee haw! We have proper emoticons now!)
We can adjust these limits, but I would rather leave them at their default settings while we get used to the system.
reply to myself
but need to get some more words typed
The 15 char limit is configurable, we think the 15 limit is a sane default that helps reduce noise.
