Goddess worship

I am:

a. signing on to the cults of Ruby- and Bella-worshiping, and happy to be part of three such wonderful cults; and

b. available for worship myself, if the mood strikes anyone. Only experienced worshipers need apply, however.

Why does the spellcheck prefer 'worshiping' and 'worshipers' to 'worshipping' and 'worshippers'? The former look odd to me...
