Thanks guys. I appreciate the response. I installed Splitbrain and while it appears on the installed plugins listing, I get this response when I try to drill in on the "info" button.
Plugin: splitbrain-dokuwiki-plugin-swiftmail-34f8ded
? Source::unknown
? Installed::unknown
This plugin returned no information, it may be invalid.
However, sending mail is only an issue because I was trying to get the WIKI to e-mail to me the administrator password, which I have (not very cleverly) lost.
I'm trying to use the procedure documented here:
http://forum.dokuwiki.org/thread/2778
Rather than changing topics in this e-mail thread, I'm going to post in that other thread as to what I have done and the results.
thanks again.
