Hi Beth,
I would do thorough testing before deploying it to production just to make sure the pre-compilation process did not result in any anomolies and that all features still work as expected. I'm not really officially recommending this solution, it is not something I can support very well if people have any problems that I cannot produce without doing this pre-compilation. So I'm not saying this is a supported way to deploy mojoPortal, it may work well or it may result in strange bugs, but if it does result in strange bugs there is not much I can do about it since mojoPortal is really a web application project not a web site project and web application projects don't support that fully pre-compiled output. So this pre-compiled deployment approach is a your mileage may vary kind of thing.
Best,
Joe
