Skyscrapercity.com
SkyscraperCity, also known as SkyscraperCity.com, is the world's largest online forum on skyscrapers and urban related topics. The website, which currently runs on XenForo, was founded in 2002 by Dutch economist Jan Klerks running on vBulletin, in order to share and solicit comment on urban development in Rotterdam. It gradually expanded to include other city and country subforums, eventually encompassing the entire world.

Torstar
Torstar Corporation is a Canadian mass media company which primarily publishes daily and community newspapers. In addition to the ''Toronto Star'', its flagship and namesake, Torstar also publishes daily newspapers in Hamilton, Peterborough, Niagara Region, and Waterloo Region. The corporation was initially established in 1958 to take over operations of the ''Star'' from the Atkinson Foundation after a provincial law banned charitable organizations from owning for-profit entities.

Online Forum
An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible. Forums have a specific set of jargon associated with them; example: a single conversation is called a "#Thread, thread", or ''topic''. A discussion forum is hierarchical or tree-like in structure: a forum can contain a number of subforums, each of which may have several topics. Within a forum's topic, each new discussion started is called a thread and can be replied to by as many people as so wish. Depending on the forum's settings, users can be anonymous or have to register with the forum and then subsequently login, log in to post messages. On most forums, users d ...

Skyscraper
A skyscraper is a tall continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least or in height, though there is no universally accepted definition. Skyscrapers are very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces. One common feature of skyscrapers is having a steel frame that supports curtain walls. These curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete. Modern skyscrapers' walls are not load-bearing, and most skyscrapers are characterised by large surface ...
