I've used LaTex notation in the past on this forum without problems. Now, every post I view says I've exceeded my equation quota and need to license Codecogs. Is this true? I don't use LaTex much and primarily only for this forum. I'm definitely not paying $200/year for this. 2. ## Re: Need to buy a license to Codecogs? I think you need to use dollar signs instead of the [ tex] and [ /tex] 3. ## Re: Need to buy a license to Codecogs? Thanks jschoeppler. That helps a lot. I wonder why the LaTex editor with tags suddenly became a license issue? 4. ## Re: Need to buy a license to Codecogs? Not sure. I'm new to using LaTex. Stack Exchange Mathematics has a really good system for using LaTex, though. It shows what your code will look like before posting. It is really helpful for somebody who is new to writing math in LaTex. However, they're rules are a little much for me. With this website, I find that I have to post and then keep editing and saving my code in the post until it shows up the way I want it to look. Do you know of a way to see what your code will look like before posting? 5. ## Re: Need to buy a license to Codecogs?

The message means that this website has exhausted its license for that particular latex interpreter. If anyone it is the website owner that needs to purchase a license not any of the site users. As others have noted there are other latex interpreters that are still accessible they just require different delimiters to activate them.

And, in order to see "what your code will look like before posting", you can always click the "Go Advanced" button to preview your post.

Ah, HallsofIvy - you beat me to it.

But maybe I can return jschoeppler's favor to me by expanding a bit. It may be obvious but no good deed goes unpunished.

When you click on Go Advanced (lower right corner of a Quick Reply) you can see the Your Message entry pane and above it is the Preview pane. After you enter data and LaTex commands (the backslash functions) with the dollar signs on front and back, scroll down and click on the Preview Post button and the top pane will show you how it was interpreted. When you're happy with the message you can then click on Submit.

Looking at the codecogs.com site it looks like this might not really be a license issue. Other people are reporting the same problem. The Latex interpreter/renderer seems to be gone from their product list.
