I was reading quite a few questions today and something I noticed was the tag "wesleyanism". Although I immediately understood it, it would not have entered my mind to call it that - I would have called it methodism as this is the commonly used word for all things relating the the churches set up around Wesley's principles. It is only a matter of time before someone tags this so I thought I'd pre-emptively make a tag synonym but then I couldn't figure out how to do it.

How do I make a tag synonym? Do I have insufficient reputation to complete this task? If so can someone else make it?
