According to this, we need 1250 reputation to create a tag synonym.
Due to the 200/day limit (which doesn't include accepted answers and bounties, but bounties can't be added yet for another 2 days), it will take some time for someone to reach 1250 reputation.
This question has created the tags: density-functional-theory, which can be a synonym for the existing dft tag, and ab-initio-calculations which can be a synonym for the existing ab-initio tag.
- Perhaps we can wait a few more days (200 x 5 days = 1000 reputation, plus bounties and association bonus, could get someone to 1250).
- Or we could have these synonyms created by CMs (although we don't want to be too much of a burden to them!)
- Or we could have this made possible at an earlier reputation level for Private Beta, due to the 200/day issue which makes it impossible to reach 1250 points right away (however I assume this idea has already come up in the past and hasn't yet been implemented, so I'm wouldn't really complain if this doesn't happen).
