You will need to keep "minutes" of meetings of what you authorize someone to do, the more detailed the better and also I suggest having a "cut-off" limitation to any memeber being able to conduct business or purchase items, without approval by all memebers, like buying stuff up to $100.00 without special consent...what ever works, but beware, authorizing someone to buy building materials for example for a large amount (like a percentage of your line of credit or capital account) may infer more responsibility with that one memebr and effect how management is viewed or liability situations, so keep cut-offs reasonable for day to day stuff and authorize major tranbsactions.
