[boost] Seems like I need write-access to merge a PR

Hi, It's been a lifetime since I last worked on Boost, and I'm lost as to the current procedures with the repository. I've been looking into this open ticket: https://svn.boost.org/trac10/ticket/12972 and noticed this open pull request: https://github.com/boostorg/numeric_conversion/pull/7 but even though I'm logged with my Github account, it appears I don't have write-access to merge this PR. I tried the wiki but seems to have way too much information. Can you simplify the steps needed, these days, to fix a bug on a library? specially if someone else already created a PR as in this case?
