How can i modify a thread?

Last month I posted a thread in Services -> Programming section, now I need to update it with recently done projects but I can't find any option anywhere, can anyone help me?

 

The edit button expires after some time mate, yours has gone now, so now you need to start a new topic/post to show any done projects !

 

Will it be considered as bumping, if i add a post in my own thread? though I just want to update my thread and get more work by showing my recent projects

 

I think not mate, since it's not a senseless bump

 

you must put on your thread an image hosten in another site so you can
update your thread by changing the image

 

Thank you all for replying me back, i request moderators to close this thread
