I'd like to present the finally-cared-about less-memory-whoring brand-new shiny version of GetLink. It's brand new and shiny because it's been rewritten from scratch, with much memory concerns in mind, and using the wonderful Ace backend.
GetLink's purpose has always been to be a link manager that isn't a memory whore. Without a database, nothing was saved, meaning less overhead. However, GetLink did the exact opposite. Saving the technical jargon, it ended up, after getting half a dozen links, using as much - if not more memory than an addon that saved links.
The newest version of GetLink hopes to solve all that. After a good bit of thinking, I've made a system of temporarily caching links and accessing them so neither is much of a memory hog. In other words, it's faster and lags you less :-)
The only difference upfront is that to get a link, it's now /getlink get <search>. /getlink (and /gl) has more options now, including managing the faster, built-in bot.
