Online message boards with sticky notes

Many people like sticky notes. I love them too and use them as bookmarks or reminders.
Today we can use virtual sticky notes on virtual message boards. The choice of the tools is rather wide. Here are my favourites - all free to use.

The simplest message board is Corkboard which is what it says it is - a corkboard with plain yellow notes.
The tool is so down-home that it does not even have its own logo.
No registration is required. Open the page and start posting your notes. It can now be embedded on your site.

Another message board which does not ask for registration (and can be used instantly) is the well-known Wallwisher. It has a small range of features (variable background, changeable colours, the possibility to add links to images, videos, music.

One more message board which uses a virtual corkboard (and looks confusingly similar to Corkboard) is Listhings but it has taken one step towards more variable notes - you can change their colour.
You have to register to use Listhings.

The site for online stickies Linoit stands a level higher with its appearance (a variety of colours and shades) and features - you can add an image, upload a video and attach a document. You can create a group and use the canvas together, embed the canvas on your blog or send the stickies by email. To use it you have to register but it is neither complicated nor tedious.

Pindax is a fun real-time alternative to the traditional message board. You have to sign up for free and start posting. It has a lot of features, like posting images, files and polls in real time. You can send your posts by email.  There are various options for using your message board. 

As the creators have stated, Pindax can be used as

1) a forum for your website
2) a collaboration tool
3) a portfolio for your designs
4) a place to chat with friends
5) a place to exchange ideas
6) an internet clipboard
7) a comment collector
8) an event planner
9) an alternative to E-Mail.

Finally, my latest "discovery"  Squareleaf is a simple and intuitive virtual whiteboard, complete with all the sticky notes. It is not as versatile as Linoit or Pindax but it is perfectly usable for the usual purpose - to remind, organise, keep up-to-date, track things etc. Registration required.
