I will contact the sire moderator about the technical difficulties you have experienced perhaps you should too. Does the constitution include provisions about terminating the club? Most club constitutions would do. If not then the committee will need to come up with a proposal, the most obvious being distribution to the members in equal shares or a donation to an agreed charity. If the committee have the power to do this then they can decide, otherwise the members will need to agree. A distribution to members could be done without agreement of all the members but anything else (in the absence of specific powers for the committee) will need to be agreed.
