does the mobil site have search function??
 

Where the heck is the search function and where do I click on to see all my recent post and threads for the week? Like on the normal web site?

Yes it does.

To use the search function from the new posts page, the word "search" is a link or there is a search link in the upper right corner that's hard to see. From there you can search date ranges and key words.

Your subscribed threads are in your user CP. Open the link to your PMs and at the bottom you will see the forum jump menu. There you will find the CP link and other stuff.
