Forum OpenACS Q&A: Response to building new Track&Field web/database application

I would consider using oacs 4.5 as soon as it is released (not too far away I believe...)

I am running a 3.2.5 site and am overly happy, but there is not as much development on it as on 4.5... And although you might not need 4.5 at the moment you might want to use packages in the future that will only be available for 4.5+!
