First of all, Welcome to the PentaxLife Forum!
We have tried to make it clean and simple. At the first look, it differs from the most forums and bulletin boards, but it is just much easier to use. PentaxLife Forum lacks a load of useless features. It has only one feature and only one goal: to help you talk about photography and photo equipment. We hope you will enjoy our forum.
Q: How do I paste photo into post?
A: If you want to share you photo (or any other image), upload it on your own blog or Flickr/PBase/etc. account, copy image location into clipboard and then type the following in your post: <img src=", paste your image url and type " />. All the code will be something like <img src="http://some-site.com/some-folder/some-photo.jpg" />. Please avoid posting images more than 680 pixels wide. If you need to show bigger picture, just paste its url into your post.
Q: How do I subscribe to the new posts in the particular thread?
A: In the end of each thread you can find a link to thread's RSS feed. Add it to your feed reader and you will never miss any replies or interesting posts. Also you can mark any thread as your favorite and subscribe to your custom RSS feed at the "Favorites" page of your profile.
If you have any questions, feel free to ask.
