Yesterday I created programmable-gain-amplifier (and added the tag info for it) after I answered a question yesterday about such an amplifier which used pga. There are a few questions which use the shorter tag and which could/should be tagged with the new, longer one. I could edit these questions individually in order to change the tags on all of them, but since "PGA" is a common acronym it seems likely that users will continue to tag questions about PGAs with pga. Therefore it seems like a good idea to make pga a synonym of programmable-gain-amplifier. However, I cannot suggest this synonym (I don't have a score of 5 on the tag), and in my experience tag synonym suggestions tend not to be reviewed for a long time (if ever) since they are on a separate page.
Would a moderator kindly merge the tags and make them synonyms, with programmable-gain-amplifier the master tag?
