Newt is right.
Also, it is the second time users have to tell you about such topics of yours.
DO create your own blog, you'll be able to cover all your various interests !
Keep the usage of scirra's forums for getting feedback on
* games you MAKE (not just think about)
* actual game designs ideas
* technical questions related to Construct 2 and game making.
The rest of your interests will fit better on your personal blog to the audience you manage to cater.
Also, please, use the pen icon in the top right of posts (Edit function) and don't post several posts in a row. Always prefer to edit.
Finally, before posting, read other topics from the forum you want to post in and ask yourself if you are really adding something valuable to this forum and is it about the same kind of subjects as the other topics.
Thank you for your consideration.
