I have created the Reffell Name Study at:
https://www.wikitree.com/wiki/Space:Reffell_Name_Study
Please be aware that there is also a Ruffle Name Study, which has Ruffell as a variant. You may like to discuss with its coordinator how you are best going to work this. A redirect (link) can only go to one Study.
You can reach the companion category page by clicking on the phrase 'Reffell Name Study' among the categories at the foot of the page. This is a list of all the profiles you include in your Study.
Your category will be [[Category:Reffell Name Study]]
and your sticker will be {{One Name Study|name=Reffell}}
and living members of your Study will be able to put {{Member|ONS|name=Reffell}} on their own profiles
I am still listed as the profile manager; I do not have your email address to put you on the Trusted List. So that you avoid spam, do not put it on this forum. Instead, send me a Trusted List request from your Study; then I will have your address and can complete the creation.
Please visit the ONS Project page, which will give you some ideas of what to do next:

Note to self: Edwin needs the ONS badge plus redirects to Reffell and Reffold
