We live in a totally time dependant world.
The world of webapp development depends on it.
I have been looking at all the mysql/php calendar modules on the net (as the project I'm working on totally revolves around time/planning/co-ordination etc etc.)
I don't think (from a developers point of view) that there is an integrated workable solution out there.
If WA could deliver a calendar plugin (i know you's guys can do it, cause your the best) it would set WA so far ahead of the competition it would make them look like kids in a play pen.
From my point of view the calandar plugin is the missing link to the WA suite and one that could be pivotal in certain other products stemming from it.
Wow imagine that !
I'd like to have the honour of being customer #1 to buy it, ok !
PS I'm really excited about the new version of CSS Sculptor coming soon !!!
