I have alternative accounts of Djm-mobile, Bigdelboy, & Deirge Ó Dhaoinebeaga. The former is primarily for editing in insecure locations where I do not wish to use my main login: particularly libraries. The second is more for specialist bulk work and has additional privileges I don't wish to have activated on my normal account. The last is intended for use on the Irish Wikipedia so I can use it without being bugged from alerts from the English Wikipedia or Commons.
