Natalia ...
Just sent Lisa a message ... maybe poll you 2 ladies ...
Anyways ... it really is up the the ladies themselves. As far as etiquette. I think the main thing. Is only do what, you feel you can give your time to.
Some ladies enter a lot. Then do nothing, pulled between to many. Some ladies will only do one at a time. To be able to give full attention, and focus on that single one.
Basically up to you, and what you feel comfortable with being in single or at same time.
There are rules.. for people posting/ running polls. Yet fairly releaxed, for ladies being part of them.
