(Sorry for double posting, i can't put the entire thing in one post on my phone)
Don't use more that one script (js, php, vbs, etc.) per page, it takes forever to load.
Put all of your formatting into ONE external css file (css files that came with something that you got (like a dropdown menu) somewhere else and put on your site are an exception). It makes everyone elses life easier.
ETC, ETC, ETC.
Basically the intent was to make ONE 'ultimate guidelines in building a site' thing. Everyone's opinion put into it ONE big guide on SPPf. Compile everyone's opinion into the ultimate guidelines to post. Sort of like what W3C does with web standards, but as something on a MUCH smaller scale, smaller audience, smaller value (it is for SPPf general purposes in this case, not for the world).
Are you getting what i'm saying now? Did this help?
