Is there a reason that all the themes literally echo the html, rather than returning it via the function. I know this currently isn't the way XOOPS is coded, but was wondering about the advantages/disadvantages of the current echo method...

Been digging around lately and it has me wondering. On that topic, it would be nice to setup a section about why stuff is being done the way it is, for those of us desiring insight into XOOPS at a non-core code level.

all (most?) output is rendered thru the Smarty template engine, and don't use any echos in the PHP code, thus separating coding (application logic) and presentation.

Oh, I see, so it mostly echos the first time around. Just based on a general looking at the themes, they all seem to echo. Hmm... are there any architecture guides as to how/why the core is setup.

nm, found it. I'll stop posting silly stuff until I have read up...
