I cam across this blog/site today that seems like an interesting tool for those who are new to ArcGIS and a nice reference for those more familiar. GIS Pathway.com is a site that offers tips on using ArcGIS (Desktop only so far). It is maintained by a student named Timothy at Central Piedmont Community College in Charlotte, NC. With the combination of written descriptions and a smattering of videos I think the site has great potential and is similar to what I had envisioned for the VerySpatial HowTo section that we never had the time to get off the ground. I really think that this is a great model for the NGTC to look at, especially since CPCC is one of the member institutions.
Check out this site and if you are on Twitter you can follow Timothy on his gispathway account.
