I was trying to get some information and I make some search and this is what I got.
https://bitcointalk.org/index.php?topic=14356;wap
The view I was getting was plain like mobile version of the forum but when I removed the ;wap, it went back to normal forum view.
The
;wap part of the URL is a legacy parameter that allows you to view a page on the mobile version. Years ago, this was very useful for older phones with limited browsers and slow internet connections. It only allowed users to view the page to read posts so users couldn't use it to write post.
Then the new version came Which is
;wap2 that allowed user to create posts although it wasn't as good as on a PC it was still a useful feature for those who used phones.
