Actually, there's no need for br tags. You can just use the carriage return.

This:

line 1
line 2

Displays:

line 1
line 2

Do you have an example where a br tag is needed ?

Yeah carriage returns will do line breaks, but like other whitespace consecutive ones aren't respected. Where I'm using the br tags is mostly after wiki tables, where there's an unattractive lack of whitespace between the table and the, say, h2 that comes after it. So, I really only need it for vertical whitespace, not just line breaks. I'll do an example here...

And this is a header¶

There are three carriage returns between the table and the header, and I don't seem to have a way to add actual whitespace between them.

Your issue might be better handled by modifying the wiki's css styles to add margins to the bottom of tables and/or the top of the headers. Are you finding you need extra whitespace after something other than a table?

r1259 made me happy - if no one else wants br tags, this issue is safe to close.

+1 to allowing ALLOWED_TAGS be editable in the admin, per project.

+1 to allowing ALLOWED_TAGS be editable in the admin. I use blockquote all the time to reference quotes and it's hard to use the Textile bq. on every paragraph. Should have the same rules for issue descriptions.

+1 to editing ALLOWED_TAGS. I need to have line breaks in tables and now I have to monkey patch to allow br's.

+1: I am also looking for a way to have line breaks within table cells.

+1: I see many reasons why consecutive line breaks should be respected: readability, page layout, respect to copy&paste structure of text files such as logs, traces, etc... well, all pertain to readability in fact...

Maybe convenience as well: we should expect people updating wikis not all being web developers but MS Word and the like users: with the tools they are used to, when they press <return> several times, it puts space between their lines of text. It's basic and it's the most straightforward way to adjust page layout.
When they (well me too!) do the same in Redmine's wiki editor, I think they expect the same behavior, especially since they can enter blank lines in the editor...

Besides this, thanks to Redmine's Team for the very nice software

+1: for advanced wiki formatting <div> is essential

Any update regarding this issue?
I am using Redmine 0.8.4.stable.2819 and my html tags are not interpreted. E.g.: <br /> doesn't put a line break. (seems to be the case here too)

Any possible changes I could make in redcloth3 configs?

Put the following in an initializer:

RedCloth3::ALLOWED_TAGS << "br" 

Thanks a lot, it worked perfectly fine.
