No doubt, but the original poster was wanting it for SEO purposes. I don't know for certain, but I'm pretty sure that hiding certain sections of pages from a search engine would have a negative impact on SEO.
But then again, since the conditional would be implemented in PHP, I'm not sure how a search engine would KNOW...
I'm pretty sure it wouldn't hurt SERPS because the HTML is just never rendered and the spider wouldn't know. The same technique is used in vBSEO's signature hide hack which disables signatures for guests which also disables it for spiders. Used properly, a conditional like this would greatly benifit boards/sites.
amykhar, I would really appreciate it. 3.6 is fine as I am sure it will most likely be backwards compatible, if not, I'm sure I could manage.
Well seeing as it might be possible, I guess I'll start a mods request thread.
