how can i mark the thread which i visit last time.
 

When i visit some thread and if i found the interesting thing about the thread then how can i did any mark so that i easily view again. I Think Bookmark is not so helpful for it in this forum.

Please suggest , i am using less time in this forum.
Please make use of time.

Click on Thread Tools > Subscribe to this Thread at the top of each thread. Then you can view them in your My LQ subscription panel for you're profile.

I have moved this to Website Suggestions & Feedback

You don't say how you are viewing the forum: imho, the best way is to get an RSS reader (akregator, in my case, but thread readers that are native to other GUIs than kde exist) to deliver to you new threads to your desk.

In that case, the answer is 'mark as important', which is available as a right mouse click and the submenu pops up.

I don't think a subscription or feed is going to help find an inactive thread. For that I think the tagging system would be the right thing if OP feels that bookmarking is not workable.

Your tag could either be a reminder of the subject/content; something personal, e.g. "dina3e", "dina3e-mark", etc.; or both.

BTW, in standard English we always capitalize "I" used as a pronoun. HTH

what you mention about tag is good but from the forum concern it may not good i think , is there any solution that may help full for this ......
other wise i will go for the tagging of the threads.

Why would Bookmarks not work? In Firefox, you can create a Bookmarks folder, name it something like "Interesting LQ Threads", then place all of them there to reduce the clutter in your main Bookmarks menu. If you're planning to save many, many threads, you can create subfolders and name them according to the thread name, etc. I'm sure other browsers offer the same capability, and IMHO, that would give the quickest and easiest access to the threads.
