It seems to me that many of the reseller plans which give you a lot of space for you to divide up give small allowances. Have you had any problems with this, because you for example have to limit your plan resource allowances? It seems like you could only fit 30-40 reasonably sized plans on one of these reseller accounts, and that's being generous. Is this it? Or did you move on to a dedicated server, or did you buy an additional reseller plan?

It all depends on your business needs .. i am moving out to a dedicated after selling about 600mb of space to 21 accounts

if you are happy with your current reseller provider then it makes sense to buy more space from them

Also, maintain open communication with your reseller provider about your growth and your plans and when you approach the limit of your reseller account then he can provide options. Those options normally will include:

1-Another reseller account
2-A move up to a larger reseller account
3-A move up to a dedicated server.
