I post a link to the tab in a reply. The little formatting box with the chain-sort-of-thing lets you put an active link in a reply.
You could also check to see if the tab is here at Big Bass Tabs, and if not, submit it so that it is. Please include any ‘tabbed by’ type info to acknowledge the work someone did. Cheers.
if i use tab i found elsewhere i credit the author. however usually i change a few things that i felt they did incorrect too. so the odd tab is part mine part theirs. but yeah
