Frankly I don’t see the need for what you want as on most occasions the link itself gives out what the topic is about & if you want to know more why don’t you click on that link & read as that is what has to be done anyway. or do you want to be spoon fed like a small kid. Also I don’t see the need for pasting the body (even a part of it) of the link & wasting space on the DF server. Did you think of that?

If you don't like what I have posted go complain to the admin as I stand by what I say.
PS I don't care if I get banned for this post.
Ho my, I'm sorry if you got offended. but let me explain why this is required.
1. The user needs to know if the content in the link is of any interest to him or her, the link title itself may not provide enough information.
2. Many users may not have the access to the link provided. (In my case.. The office firewall).
3. Many users may not have enough bandwidth to open the site (Mobile Users) , its light on pocket to read quoted text in a thread rather than going to that website and realizing that it contains loads of ads.
4. RSS Feeds users (including myself) . 75% of the time I use RSS feeds for the websites I visit , that includes TDF. if the content of the thread is interesting, then I would visit the forum and contribute to the thread. else would just delete the entry from the RSS Reader. If there is no content in the thread.. then I would not be interested in visiting the thread right?
5. At last . I dont trust any of the links provided in open forum. specially when url shorteners are common these days. Check this link
I hope my fellow forum members would agree with me in WRT the above points made.
