capricorn, go to the thread(s) you created and you will see under your username on the left is a white triangle outlined in red with a black ! in it. Click on it and a screen will come up for you to "report the post". Explain that you wish to have your threads removed and click "send". This will go to our moderator/administrator team and they will be able to remove them for you.

Also, like ECHOES states, sometimes it's a matter of posting in a more specific forum that may get more views and responses. I hope you have given enough time for folks to respond. Sometimes members need time to think of how they wish to answer another member and sometimes our members who most often respond are not online every single day but will catch up when they do come online.

Take good care!
