[Req]mybb htaccess

Hello guys

im learning about how to make a .htaccess but i find it difficult with mybb i tried a lot to change threads/forums urls and the pages like misc.php?page=[pagename] to simple one with the htaccess but i failed everytime

so im just requesting simple tut about how to make a .htaccess without google SEO(the original mybb htaccess.txt)

1. threads and forums ---> domain.com/thread/[threadname] & domain.con/forum/[forumname]

2. users and calendar domain.com/user/[username] & domain.com/calendar/[day]/[month]/[year]

3. pages and tabs(mytabs plugin)
original pages link: domain.com/misc.php?page=[pagename]
make it to: domain.com/[pagename]

original tab link: domain.com/index.php?tab=1
make it to: domain.com/tab/[tabname]

thats all i will be thankful if someone tell me how to make it cuz in fact i want to delete my htaccess and make a new one

and thanks all respect to mybb users and staff team
