I don't see any faults with the name, but at some point Tiny Portal may become more like a CMS.
Back in the day, I used something called Subdreamer CMS, which was basically a partal with some nice feature but still very limited.
Tiny Portal is brilliant, it does come with a learning curve for me but once you start making headway things come together. It also helps that there's people who care about TP/helping others.
If say it's better than IP.Pages which at the beginning I couldn't work with. The databases and templates aspect would be awesome in Tiny Portal but aside from that TP wins hands down.
PS. The back story was interesting, I recall the early days of SMF but I don't recall using TP before. I actually thought it was a portal for other free forum packages. Not sure what I'm mistaking it for!
