a license. Currency requirements apply.

Here's a question. I'm a private pilot, ASEL. If I get my glider
rating, will I have to do a separate BFR for each (powered and glider)?
If not, is would it just be a matter of currency (3 takeoffs and
landing within past 90 days if I want to take passengers)?
