Re: [Phpwiki-talk] ansi sql

[Brian C <br...@be...>]

Hi,

Either your enthusiasm will bring new life to what looks to me to be a 
dying project or it will fall on deaf ears. This list mainly receives 
spam right now and actual questions about phpwiki tend to go unanswered. 
My installation has been broken for months, searching on Google shows 
many people have the same problem, but I cannot get any info on a fix. 
See 
http://sourceforge.net/mailarchive/forum.php?thread_id=8990578&forum_id=4517

I believe my solution is going to be to move to mediawiki, despite the 
extra work this will create for me, because it is possible to get 
support for it. Since Wikipedia uses it there is regular development, 
and its markup format is becoming something of a standard.

If this project does want to remain viable that's one thing it should 
seriously look into: a script to convert phpwiki markup to mediawiki 
markup and then an adoption of mediawiki markup style in a new version.

Good luck to you,

Brian
