would like _blank on all post links

Hi there peeps ..... I would like all the post url links to be all _blank so my site tab stays open.

I know there's a code i can put in the header that will make ALL the links do it, menu links etc etc which won't work for me, so would someone make me a code please to do this ?

 

Also i think this should be added to your next elgg version as it keeps our sites tabs open which is important for views etc etc etc  

 

thank you :)
