Re: Financial Obligations and Sensei
Your group needs to become a non profit group and get a treasurer to keep track. Set your mat fees to match the financial needs of the dojo. Spread out the dojo jobs among your board members and let your sensei do the teaching, and not have to worry about the dojo business. Hopefully, your sensei is able to support himself, or if not you will need to build in a salary for him (good luck with that). Most sensei's I know are volunteers. (unless they work at aikido full time and have a big dojo)
e ya later
PS btw: I'm not meaning to insinuate this is the only way to go, but it makes sense to me and works pretty well at our dojo.
