Please upgrade to 2.3 here.
The 2.2 and earlier branches are no longer being updated.
How can I disable the dreaded smileys in 2.3.1? [RESOLVED]
The smileys somehow flew in under the radar. Only just found out they're there on typing a colon. Good grief, we can't have that, that's far too childish. Yet I can't see any obvious way of turning them off. Anyone help?
