There are several Excel forums for any language in the world, with some 10 comments a day, each.
On the other hand there is only one active Visio forum in the world with ca. 10 comments a day...
I think most people are not aware about the power behind ShapeSheet, Data & Databinding.
You don't need a forum, if you only draw sketches and diagrams.
For me, Visio is the ideal platform to implement powerful drag & drop solutions with great usability in little time.
Especially in a team with Excel.
However, here in this forum we have enough expertise to solve almost any problem within hours

And 10 comments a day, 365 days a year for > 10 years gives a valuable archive.
