turtle you're right, you have more to gain by acceding to their demands than keeping your domain.
HQ and Dontpanic are also right, but fighting that battle won't do you any favours.
Given that you've built a site and publicised your URI and all they've done is registered a domain and then sat on it for two years, it's pretty shitty of them to ask you to change when it would be so much easier and cheaper for them to just come up with another name
I would definitely follow up on the "hint" that you'll be asked to join. Play nice but firm on that - you'll go to the (not inconsiderable) hassle and expense and inconvenience and damage to your brand of changing your name on the understanding that you will now be a part of surreydoulas, with all that entails.
I know you may not have time for this, but it might make sense to also offer to get the group site up and running, because being linked from that site is going to be important for you.
Are you talking to anyone about search engine optimisation? For the group site it would be worth pooling your money to hire someone good to at least get you started with that. Then each of you is linked off, so you should all benefit from the google juice.
In the meantime you need to come up with a new name. Do you want us to help you? I'm not really offering my services as I S. U. C. K. at coming up with names for websites/projects/business ideas but I'm sure the collective MarchMums heads could maybe help with inspiration. I will add suggestions, but I recommend now that you ignore them
merryberry that picture of GG is just gorgeous
evie congratulations I'm delighted to hear your news.
HQ good news about the yoghurt.
Does anyone else have a baby that barely eats anything? At Christmas my SIL was telling me what her DS (same age) has for breakfast - 1 weetabix, 1 round of toast, 1 plum, .5 banana.
DD has: 1 mini shredded wheat, 1 grape!
I know babies are all different but if it weren't for merryberry's apple suggestion from months ago she could barely be said to be weaned
