Then once in the topic page, you will see a list of recently created threads, which lets you check if someone has already created the thread. If not, click on the 'post a new topic' box to create the thread.
Hope that makes sense!
BTW, did you see there was a Sunday fasting today topic created later, I think only 2 people posted that they were fasting. Hope your day went ok!
BTW again, if you ever have a query, try doing a search on your query. Otherwise create a new thread with that question (now you know how!) and/or tag someone who you think might be able to help.
Best wishes and good luck with this way of eating.
