Forum tag [lt] does not work

[Georg]

In my post to the problem 198 I did use some of these tags. But "[lt]" is not translated to "<". If you tell me that it is no longer supported, I'll change it to "<".

Hi Georg,

The support of [lt] was introduced because originally none of the posts in the forum were parsed and HTML was permitted. Consequently members could not use mathematical inequality notation without it being interpreted by the browser as HTML so I had to introduce the custom tag. However, cyber-vandals began taking advantage of the fact that HTML could be used and I was forced to parse all posts.

At some point recently I must have removed the [lt] tag thinking that it is now redundant because the "less than" symbol would render properly. However, I had not appreciated that older posts, and members that have got into good habits, would still require it. So it has been restored and I will definitely continue supporting it.

Thank you.
